Walter Willett of Harvard (author of "Eat Drink and be Healthy") rejectes the low end of the BMI charts based on all data, claiming that smokers contaminate the low end. He says that after pulling out the smokers from the Nurses Health Study they found the lowest safe BMI to be 17, that is people with BMIs of 17 (nonsmokers) died at slightly lower rates than those with BMIs of 21 to 25.
